Dual Inputs. Double the Insight!

“What a difference! It's accurate and I had my furnace gas pressure correctly set in about 3 minutes. I can't speak to longevity or other functions but for my purpose it was an excellent buy that saved me a lot of money!” - Bill S.

Why Get Our HVAC Digital Manometer Gas Pressure Tester?

✅Precise Dual Input System: Some meters only give you one input, which limits what you can measure. This model gives you two. You can compare two pressure sources side by side and get fast, accurate differential readings. This removes the need for guesswork and speeds up troubleshooting, making diagnosing and balancing systems much easier.

✅Wide Range with High Accuracy: Sensitive enough for low-pressure HVAC tasks but reliable enough for gas system checks. This meter reads up to ±2 psi with a tiny 0.001 resolution and ±0.3% full-scale accuracy. That means you can trust it to spot even the smallest pressure changes. Without accurate readings, the air conditioner risks running inefficiently, leading to poor cooling, compressor damage, refrigerant leaks, and costly repairs.

✅Work-Ready Display Features: The backlit screen helps you see clearly. The data hold function freezes the last reading. Auto-off preserves battery life when you’re in the field. These features are built for real job site demands.

📓FREQUENTLY ASKED QUESTIONS

Q: Does it have an auto-off feature?

A: Yes, the HVAC Digital Manometer Gas Pressure Tester does have an auto-off feature. 

Q: Is it battery powered?

A: Yes, this manometer is battery powered. It requires 1 9V battery, which is included.

Q: What is considered a dangerous pressure reading?

A: For example, if the safe pressure range is between 0 and 2 psi, a reading above 2 psi or a sudden negative spike could signal dangerous conditions like leaks, blockages, or system failure.
